UNITED STATES PATENT OFFICE.

UNIVERSAL COIL MOUNTING.

Application filed September 19, 1923.

To all whom it may concern:

Be it known that I, RAY E.JON1-1s, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Universal Coil Mountings, of which the following is a specification.

My invention is an improved coil mounting, particularly applicable to radio receiving sets.

The object of my invention is to provide a coil mounting in which any type of COll used in radio receiving may be quickly mounted with a minimum amount of effort.

Another object is to provide a mounting in which the coils may be adjusted either horizontally or vertically and also swung in either direction.

Other objects and advantages will be more specifically pointed out and described in the following detailed description.

In the annexed drawing in which my invention is illustrated:

Figure 1 is a front view of my mounting.

Figure 2 is a rear view of the same.

Figure 3 is a sectional View taken on line 33 of Figure 2.

Figure 4 is a sectional view taken on line 44 of Figure 3.

Figure 5 is a sectional view taken on line 5-5 of Figure 1.

Figure 6 is a side view of one of the coil mountings.

Figure 7 is a plan view of one of the coil mounting carriages.

Figure 8 is a sectional View taken on line 8-8 of Figure 7.

Figure 9 is a side elevation of one of the coil supporting buttons.

Figure 10 is a sectional view taken on line 10-10 of Figure 9.

Referring more particularly to the drawing, my coil mounting comprises a body 1 which is formed of an insulating material, and coil mountings 2, 3 and 4 are positioned upon it. The mounting 2 comprises a cylinder 5 which is journaled in the frame 6. This frame is secured to a base 7 and a rod 8 secured to said base extends into a vertical bore 9 in the body 1. A set screw 10 extends into the body 1 through a metal Serial No. 663,617.

sleeve 11 in the upper part of the bore 9 and bears against the rod 8 and holds it in the position desired. The mounting 2 may be raised above the body 1 on the rod 8 to any height desired and held in place by the set screw 10. The side of the rod 8 against which the set screw bears is preferably flattened to prevent its turning. A hole 12 extends diametrically through the cylinder 5 and is adapted to receive the rod 13 upon the end of which the coil is mounted. A set screw 14 extends into the cylinder 5 against the rod 13 to hold it in the position desired. The rod 13 is formed of either a conducting or nonconducting material, depending on the type of coil used. \Vhen the long fibre rods are used body capacity will be greatly reduced. The cylinder 5 may be rotated vertically in the frame 6, thus swinging the coil upwardly or downwardly as desired. A set screw 15 in the frame 6 bears against the cylinder to hold it in the position desired.

The mountings 3 and 4 each consist of a cylindrical button 16 which is journaled in straps 17. These straps are pivoted to carriages 18, which are slidably mounted in frames 19 secured to the top of the body 1. These frames have a longitudinal slot 20 formed therein, and a tongue 21 on the carriages 18 fits into the slot. A shaft 22 is journaled in the tongue 21 and a gear 23 is secured to the end thereof which meshes with a rack 24 secured to the body 1. A button 25 on the end of the shaft 22 enables said shaft to be rotated and actuates the gear 23 in the rack 24 to move the carriage 18 in the frame 19.

A coil rod similar to the rod 13 extends through a hole 26 in the button 16 and a set screw 27 screws into the button 16 against a nonmetallic pad 28 which bears against the rod. The button 16 is set at any desired position with regard to straps 17 by a set screw 29 in said strap.

A plurality of metallic sleeves 30 are set into the bottom of the body 1, which form plug contacts from which the leads extend from the coils to other parts of the radio set. A contact member 31 is threaded into the sleeve 30 and the wire from the coil may be secured to this member if desired and a plug top inserted into the sleeve to conduct the current away to the receiving mechanisms.

The advantages of my mounting are as follows:

The coupling of coils obtained by parallel movement is rapid and a slow motion (similar to micrometer adjustment) for finding the critical relation of the mutual inductive fields is possible by means of the gears 23.

A hinged movement similar to the honeycomb coil mounting places the coils from parallel to a right angle position.

Elevation of coils to avoid interference 1 with other units; in and out movement for alignment of coil centers; rotation on axis for variocoupler and variometer use; and a combination of movements for reflection, and so forth.

Rapid rearrangement of parts for expert mentation; table or cabinet mounting; concealed surface and plug connections pro- 'vide rapid means of assembling the units in new hook-ups. One mounting for any make of coil takes the place of many. Elimination of mechanical work in combining coils. Greater efficiency by preventing dead end losses; elimination of parallelism by using short'flexible conductors; placing coils to minimize interference; decreased body capacity effect by using long fibre contact rods.

Having described my invention, I claim:

1. A coil mounting comprising a body, coil mounts positioned on said body, means to secure the coils to said mounts, means to swing said mounts on either of two axes at right angles to each other and means to move said mounts at right angles to one of the said axes of rotation.

a. A coil. mounting comprising a body, coil mounts positioned on said body, means to secure the coils to said mounts, carriages upon which said coil mounts are positioned, a gear journalled in said ci'irriage, .a rack with which said gear meshes, means to swing said mounts on either of two axes at right a1 gles to each other and means to rotate said gear to adjust the mounts at right angles to one of the said axes of rotation.

A. coil mounting comprising a body, a cylinder, a frame in which said cylinder is mounted, means to adjust said frame relative to said. body, means to mount the coil on said cylinder and means to swing said cylinder on either of two axes at right angles to each other.

In testimony whereof I affix my signature.
